2 Claims. (Cl. 215--86) This invention relates to a removable closurefor a bottle and more particularly to a sealing closure for a bottlecontaining a carbonated beverage or the like.

An object of this invention is to provide a removable and reusableclosure for a bottle which forms a firm double seal to prevent escape ofcarbonation.

A further object of this invention is to provide a closure member havinga plug which fits into the neck of a bottle and which is forced firmlyagainst the inside of the neck by pressure inside the bottle.

A further object of this invention is to provide a closure member ofthis type having a plug of elastomeric material provided with acylindrical skirt portion which is firmly held against the inside of theneck of a bottle by pressure inside the bottle.

A further object of this invention is to provide a closure member ofthis type having a retainer member hinged to the plug, which retainermember engages the bead at the mouth of the bottle to hold the pluginside the neck of the bottle.

From the following description and the accompanying drawing, the aboveand other objects and features of the invention will be apparent tothose having ordinary skill in the art to which it pertains.

In the drawing:

Figure 1 is a perspective view showing a bottle provided with a closuremember constructed in accordance with an embodiment of this invention;

Fig. 2 is a view in section taken along a line lI-II in Fig. 1;

Fig. 3 is an exploded view showing the parts of the closure member;

Fig. 4 is a view in section taken along a line IV-IV in Fig. 3; and

Fig. 5 is a view partly in side elevation, and partly in section showinga bottle having a closure member constructed in accordance with anotherembodiment of the invention.

In the following detailed description and the drawing, like referencecharacters indicate like parts.

The closure member shown in Figs. 1- r inclusive includes a one-piecebody 10, a retainer member 12, a pivot pin 13 and a pin-retaining disk14.

The body may be formed of rubber or other suitable elastomeric material.The body includes a cylindrical cap portion 16 which overlies the mouthof a bottle 17, as shown in Fig. 2, and a cylindrical plug 18 which fitsinto the bottle through the mouth thereof. The inner end of the plug isconcave as indicated at 19 so that an annular or cylindrical skirt 21 isformed. The cylindrical portion 21 is adapted to be deformed or spreadby pressure inside the bottle to cause the cylindrical inner end portionof the plug to firmly engage the inside surface of the neck of thebottle 17. As shown, the plug is provided with an annular groove 22between the inner end portion of the plug and the cap to allow thecylindrical inner end portion to flex sufliciently to provide agas-tight seal.

The upper end of the cap portion is provided with a PatentedNov. 13,1956 ice counterbore 23 surrounded by an annular rim 24. Aslot 26 (seeFig. 3) is formed in rim 24 and across a diameter of the cap portion toreceivethe pivot pin. 13, as shown in Fig. 2. The pivot pin 13 is heldin place :in the slot 26 by means of theplate 14. The inner end of thebore 23 is undercut as at 28, in- Fig. 2, to receive and hold the edgeof the plate 14, whereby the plate 14 in. turn, holds the pin in theslot. The plate may be decorated with any appropriate indicia, such as atrademark, slogan, or the like.

The retainer member 12 is pivotally supported: on the pin 13. As shown,the retainermember 12.is substantially half circular in cross section orU-shape, and. is provided with openings 29 and 31 through which the endsof the pin 13 project. A flange 32 is formed on the edge of the retainermember 12 remote from openings 29 and 31. As shown in Figs. 1 and 2, theflange 32 swings beneath the head 33 at the mouth of the bottle so thatthe retainer member holds the body firmly in position, as shown in Fig.2. The upper edge of member 12 is provided with a flange 33 for limitingthe swinging or turning of the body member with respect to the retainermember 12.

When the closure member is inserted in the mouth of the bottle, as shownin Fig. 2, a double seal is formed, there being a seal between the capportion 16 and the lip of the bottle, as well between the cylindricalinner end portion of the plug and the inside wall surface of the bottleneck.

In Fig. 5 is shown a modified form of the device. The device in Fig. 5corresponds to the device of the other drawing with the exception thatinstead of a pivot pin, an elongated member 35 is employed having apivot pin portion 36 which extends through flanges of a retainer member37 and through the cap portion of a body 38. One end of the pin portion36 is integrally formed with an elongated hook or support member 39. Thehook member 39 extends away from the closure member and forms a supportby means of which the closure member and the bottle may be hung from anappropriate support 41 or the like.

The bottle closures illustrated in the drawing and described above aresubject to structural modification without departing from the spirit andscope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A removable closure for a bottle having a neck, an open mouth at oneend of the neck, and a bead on the outside of the neck spaced from themonth which comprises a one-piece body of elastomeric material having aplug adapted to be received inside the neck of the bottle and a capportion for overlying the mouth of the bottle, said plug having anannular groove between the inner end thereof and the cap portion, theinner end portion of the plug being cylindrical and engageable with theinside surface of the neck of the bottle, the surface of the inner endof the plug being concave, thereby rendering the cylindrical portiondeformable by pressure inside the bottle to firmly engage the innersurface of the bottle neck, the cap portion being provided with adiametrically extending slot, a one-piece pivot pin in said slot withends of the pivot pin projecting on opposite sides of the cap portion,the cap portion being provided with a bore extending on both sides ofthe slot, an annular rim on the cap portion surrounding the bore, a pinretaining plate received in the bore overlying the pin and engaging therim to hold the pin in the slot, and a cap retainer member pivotallymounted on said pin, said retainer member having a flange engageablewith the bead of the bottle to hold the closure body with the pluginside the neck of the bottle and the cap portion in engagement with themouth of the bottle.

2. A removable closure for a bottle having a neck, an open mouth at oneend of the neck, and a bead on the outside of the neck spaced from themouth which comprises a one-piece body of elastomeric material having aplug adapted to be received inside the neck of the bottle and a capportion for overlying the mouth of the bottle, said plug having anannular groove between the inner end thereof and the cap portion, theinner end portion of the plug being cylindrical and engageable with theinside portion being provided with a bore extending on both sides of theslot, an annular rim on the cap portion surrounding the bore, a pinretainer plate in the bore overlying a portion of the pin and engagingthe rim to hold the pin in the slot, and a cap retainer member pivotallymounted on said pin, said retainer member having a flange engageablewith the head of the bottle to hold the closure body with the pluginside the neck of the bottle and the cap portion in engagement with themouth of the surface of the neck of the bottle, the surface of the inner10 bottle.
